1 Claim.

The present invention relates to a device for setting carburetor floats and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided a device for setting the floats of conventional carburetors and it consists of a substantially L-shaped body having a vertically extending portion which is marked with indicia measuring the distance from the horizontally extending portion and such vertically extending portion is threaded from the bottom upwardly throughout approximately one half of its length. Novel means is provided for mounting thereon a horizontally extending swingable arm which is normally urged in a downward position against a threaded follower by means or a compression spring surrounding the vertical member and bearing against a washer at the upper end of the vertical member which washer is held in position by means of the handle or horizontally extending portion of the body. A novel means is provided for turning the follower upon the body.

It is accordingly an object of the invention to provide a device of the character set forth which is simple in construction, inexpensive to manufacture and yet effective and efficient in use.

Another object of the invention is the provision of a device of the character set forth having a novel follower and novel means for operating the same.

A still further object of the invention is the provision of a novel swingable arm and mounting therefor, such arm and mounting both forming parts of the invention.

Other and further objects of the invention will. become apparent from a reading of the following specification taken in conjunction with the drawing, in which:

"Figure l a side elevational view of an emtmiimen+ of the invention,

Figure 2 is an end elevational view of Figure 1,

Figure 3 a side elevational view of one element of the invention shown in Figures 1 and 2,

Figure 4 is a sectional view taken along line t at oi" Figure 1.

Figure 5 a sectional view taken along line -5- of Figure 1, and

Figure 6 is an isometric view of another element of the invention as shown in Figures 1 and 2.

Referring more particularly to the drawing, there is shown therein a substantially inverted L- shaped body comprising a horizontally extending handle IB and an integrally formed vertical memher I I the lower half of which is threaded, as indicated at I2, and one side of which is flattened, as indicated at I3. The flattened portion is is provided with indicia Id which indicia denotes the distance from the underside of the handle Ill to the underside of an arm I5 which is formed integrally with a U-shaped clamp member I6 havin its bight portion bifurcated as shown at Iiia to provide a pair of outstanding ears I! through which a bolt I8 extends. The bolt I8 is provided with a nut I9.

The clamp member I6 is substantially U- shaped and surrounds the vertical member I I and has interposed between its arms a collar 20 which likewise surrounds the vertical member H.

A washer 2I is mounted upon the member II and abuts the upper end of the clamp member I6 while a washer 22 likewise mounted upon the vertical member I I abuts the underside of the handle I0. A compression spring 23 likewise surrounds the member 2I and is adapted to bear against the washer 2I at one end and the washer 22 at its other end.

A washer 24 is also mounted upon the member 2| and abuts the underside of the arm I5. A follower 25 is threadably mounted upon the threaded portion I2 of the member I I and is provided with an outstanding lever 26.

In operation, it will be apparent that in order to ascertain whether or not a proper float adjustment is extant in a carburetor, the follower 25 is first adjusted by means of the lever 26 until the indicia I4 give a proper reading. Whereupon the nut I9 may be tightened upon the bolt it to thereby maintain the arm I5 in latched position, if desired upon the member I I. Thereafter the handle I0 is rested upon the carburetor bowl and the arm I5 may then be used to test the correct height of the float, it being understood that if the float is correctly positioned, the arm I5 will just clear the same. and if not correctly positioned, the same must then be adjusted until the arm I5 does barely clear the float.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many 3 minor modifications may be made without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

A device of the character described comprising a vertical body member having indicia thereon, an integrally formed horizontally extending handle at the upper end of said body, a clam member vertically slidable and revolubly mounted on said body, a follower threadably mounted upon the lower portion of the body below said clamp member, an arm formed integrally with said clamp member and extending in spaced parallel relation to said handle, a compression spring surrounding the upper portion of said body and urging said clamp member against said follower, and a nut threadably mounted on said body below said clamp.
